What is Requirement Elicitation Techniques Like Fast?

Elicitation of requirementsis the first step to requirement engineering and forms a very crucial part of the entire process. The information collected during requirement elicitation has to go through the usual steps of interpretation, modeling, analysis and validation before the engineer is confident that the collected data for requirement is enough to work with. Thus, one can say that, requirement elicitation is very closely connected with the process of requirement engineering.

Goals Of Requirement Elicitation:

One of the primary goals ofrequirement elicitationis to find out what problems exist and need to be resolved. It is thus, engaged in identifying system boundaries. These boundaries on the other hand, define where the final delivered system will fit in with respect to the current operational environment. Identifying boundaries is very important because the boundaries of a system can affect all subsequent efforts of elicitation. Right or, wrong selection of boundaries can affect identification of stake holders, identification of user classes, identification of goals, tasks, scenario etc. It is highly important to elicit goals in the early development process. While it is crucial to elicit the high level goals in the earliest, elicitation of the lower level goals continue throughout as the development takes place. The business goals can be considered the high level goals, while the lower level goals consist of technical goals.Elicitation of requirementssometimes, becomes very difficult because of the inability of the users to articulate their requirements.Requirement elicitationtechniquesare therefore used to make the process better.

Requirement Elicitation Techniques:

There are a number ofrequirement elicitation techniqueswhich can be named as Brain storming, Document analysis, Focus group, Interface analysis, Interviews, Observation, Prototyping, Requirement workshops, Surveys and Questionnaires. Brainstorming literally refers to gathering the stake holders and brain storming to produce a large number of ideas and derive themes from among these for further analysis. Procured information should not be lost and therefore should be recorded. Document Analysis refers to gathering and reviewing existing documentation that is relevant to business objective or, may contain data that may offer appropriate solutions. Such documentations can include business plans, market studies, contract, request for proposal, statement of work, memos, training guides, procedures, competing product literature, problem reports, customer suggestion logs so on and so forth.

Gathered group of pre-qualified stakeholders offering inputs for business needs and some solutions form the Focus groups. An Interface Analysis refers to analysis and deconstruction of the way that a user interacts with an application. Or, it also refers to the way two applications interact with each other. Thisrequirement elicitation techniqueis good for software solutions which has high involvement of interactions of applications. One to one interview is a very common and preferred method of requirement elicitation. It tends to give the analyst an in depth understanding of the stake holder’s requirements. The observation technique helps when the project at hand may change or, enhance current processes. Prototyping, requirement work shops, surveys and questionnaires are also helpful techniques in the fieldof requirement elicitation.
